in the accompanying drawings which show the preferred embodiment of the present invention, there is illustrated a molding machine for forming ornamental tiles of different geometrical or floral designs, preferably for use in the construction of ornamental and fireplace walls, said molding ma- Chine embodying a `supporting structure comprising legs l arranged in pairs at the opposite ends of the frame and connected by longitudinal guide bars 2, the rear legs being of greater height than the forward legs and connected at their' upper ends by transverse channel irons 3 and Li respectively. As shown in Figs. 37 '7, and 11, the plate 5 rectangular in elevation is secured as at 6 to the adjacent side flange of the forward channel iron 4 and said plate 5 carrier its upper edge as at 'Z an upright channel iron 8, the channel irons Li and 8 extending laterally of the supporting' fraine structure with the lower angle iron 4: supported at its outer end by the leg 1a as shown in Fig. An internally threaded annular fiange 9 is carried by the inner face o-f the plate 5 for the reception of the threaded end of the cylinder 10, the inner end of said cylinder being supported upon the longitudinal brace bars by the supporting bloclrs and anchoring devlces 11.

As shown in Fig. 7, the plate 5 is provided with a central circular opening 12 having diametrically opposite key notches 13 to receive key lugs 14 carried by the guide head 15 that is positioned in the forward end the cylinder' 10, the guide head 15 being anchored in position in any suitable manner and having the forward face thereof terminating flush with the forward side of the plate 5 as shown in Fig. V11.

A further 'support for the cylinder' 10 includes the oppositely disposed channel irons 16 and 17 secured to opposite sides of the cylinder as at 18, the rear ends oi' the channel irons having their lower flanges anchored as at 19 to the channel iron 3 while an upright channel iron 20 connects the upper flanges of the channel irons 16 and 17 abeve the supporting legs 1 as illustrated. The forward ends of the side channel irons 16 terminate at points adjacent to and inwardly of the forward end of the cylinder.

A piston or plunger is associated with the cylinder to be operated for forcing` plastic material in the cylinder through the guide head 15 into a tile inold to be later described and said plurnrer`` inountingr and operating' ineans therefor includes an internally threaded block 21 secured between the channelirons 3 and 20 :in axial alineinent with the cylinder 10, said bloclr carry- V ing an annular fl'ange 22 at its inner end to the inner face of which a retaining ring' 23 having' a central opening' with a. beveled wall is attached, as shown in 2 and A spirally threaded `rod 24.- is threaded through the fixed block 21 and is longitudinally slotted upon one side thereof as at 25. A handle-frame embodying a disk' plate of the handle frame against nioven'lcnt away froin the screw blocl: 21 and peruntting` rotary movementv of the disi; plate relative to the screw block. The connection between the dislr plate 26 and the red 2-1 includes a hey or spline 28 fixed as at 29 to tl sleere 27, the key being' slidaole in the groove of the rod 24 'when said rod is moved longitudinally of the scfz'ew block 21. Handle bars 30 radiate froin the disk platc 26, While the inner end of said rod is provided with a wrench hold 31 for detachable engageincnt with the wrench or handle 32 so that said red iray be either operated by the handle bars 30 or Vthe handle The forward end of the r'od 2% has reduced cylindrical portion 33 upon which the sie-eye of the plunger head is freely inounted, anti-friction bearings 36 being disposed at opposite ends of the sleeves 3111 upon said rod end while the plunger 35 is retained on the rod end by -he nut 37. Vrlhen the rod 24 is rotat-ed through the inediuin of the handle bars 30 or the wrench 32, said rod is inoved through the screw bloclr 21 to cause the plunger 35 to enter and move through the cylinder 10 for forcingl plastic material therein through the guide head 15.

The tile inold is positioned forwardly of the guide head 15 in line therewi-th and between the. channel irons 4: and 8, the tile mold 38 being rectangular in elevation as shown in Fig, 5 and detachably mount-erV in the frame 39 by the fastening devices 40. The inole 38 has portions thercof cutaway to reduce the weight as at 4-1 while the tile desi gu is cutaway as at 427 the design opening` -12 extending completely through the inold and registering with aJ siinilarly formed opening' 42Pu in the guide head 15a the identity of the openings 42 and 4:22L being' disccrnihle in Figs. 5 and Y.

lt being the intention to forin a facial design upon the tilea the hingedly inounted frame is supported by the outer forward flanoje of the forward channel iron 4, said frame being of rectangular forination and einbodying; an angle iron 413 having the face plate Zlet detachahly connected to ono tiange thereof as at 45, the inner face of said platc Lillbeing provided with an indcnted design 46 corresponding' to the opcnino's 42- in the guide head 15 and the opening; -l the tile mold, the openi: and facial des' on the plate Llil being' shown in alined positions in Figs. 2, 3 and 11. The frame carrying' the facing; plate lili and coinprising' the angle iron 43 includes an enclosing; strip 47 secured as at 48 to the other of the angle iron 43 the lower plate frame beingI hinge'd as at 119 to the forward iiang'e of the channel iron Al-,this construction being; clearly shown in 3 and 11. `he tile mold being slidh tween the channel irons 4 and 8, centeruig;

means is provided Vfor alining the guide head 15, tile mold 38 and facing plate 44, such means including side sti-ips carried by `the hinged frame and having their inner edges extending in overlapping relations relative to the frame 39 that carries the tile mold as shown in Fig. 12.

A clainp member is provided for holding.

the spacing plate 44 in its upright operative position and asshown in Figs. 2, 4 and 12, includes an iron of channel formation having the end leg 51 pivotally supported upon th-e pin 52 that is anchor-ed between 'the upper and lower flanges of the side channel iron 16, said end leg 51 of the clamp extending through the cutout port-ion of the adjacent side of the plate 5 and is integrally formed wit-h the cross leg 54. The cross leg 54 of the clamp terminates at the opposite side of the cylinder and has a pivotal connection 55 with the opposite end leg` 56 of the clamp, the free end of the leg oe being provided with hoolrs 57 to engage the keeper pin 58 anchored between the upper and lower fianges of the adjacent side channel iron 17. To retain the hooks 57 in engagement withthe pin 58, a cross strip 59 secured to the angle iron 43 of the hinged frame as shown in Fig. 4 is engaged by the screw 60 carried by the cross leg` 54 of the clamp, the cross leg` of said clamp carrying a bearing 61 for said operating screw.

Vfith the parts assembled as above described, plastic material in the cylinder 10 is forced therethrough Vby the plunger 35 when the rod 24 is rotated, the plastic material being` forced thru 'the openings 42a in the guide head and into the openings 42 in the tile mold, a portion of the plastic material passing forwardly of the tile mold and engaging the facial design 46 upon the facing plate 44, which operation will at once be apparent from an inspection of Figs. 2 ant 3. TWhen the plastic material has been thoroughly packed in the t-ile mold, the wir (S2 that is anchored as at 63 to the forward side of the plate 5 is manipulated by the handle 64 to cause the wire to pass upwardly between the guide head 15 and mold 38 for severing the plastic material in the mold from the plastic material in the guide head and cylinder. This operation may be accomplished by releasing the end leg 56 of the clamp. VVith the clamp positioned laterally the hinged frame carrying the facing plate 44 is moved downwardly upon its hinged iounting 49 to displace the facing plate 44 from the forward side of the tile mold 38. As shown in Figs. 3 and 11, the outer faces of the upper and lower sides of the frame 39 are longitudinally grooved as at 65 into which longitudinal ribs 60 carried by the adjacent faces of the channel irons 4 and 8 eaten-d, the mold 38 carrying thetile set therein being movable between the channel irons 4 and 8 to be. displaced laterally 'of the cylinder 10 and alined with a followassociated with the side channel iron 17,

and as shown in Fig. 8, the angle iron 67 secured to the bottom wall of the channel iron 17 has the horizontal leg thereof cooperating with the upper ange of the channel iron 17 to provide a guide for Ithe rack bar 08, the upper flange of the channel iron and the horizontal legof the angle iron 67 having retaining strips 69 secured thereto for holding the rack bar 68 in position. As shown in Fig. 1, the angle iron 67 has a cut-I away portion midway the ends thereof to accommodate the rotatable mounting of the stub shaft 70 in the bottom wall of the channel iron 17, said stub shaft 70 carrying a pinion 71 that is lreyed thereto as at 72, the -outer end of the stub shaft 70 having a key or wrench end 73 for receiving the handlecr wrench 32 that is interchangeable in application to the inner end of the screw rod 24. The rack bar 68 is reeiprocable upon rotation of the pinion 71 between the angle iron 67 and the'upper flange of the channel iron 17.

The forward end of the rack bar 68 carries an outwardly. directed angle arm 74 that is braced with respect to the rack bar by the strut 7 5 and has a rectangular frame 76 secured to the forward side thereof as shown in Figs. 2 and 6. The follower 77 is of a configuration similar Vto a design opening 42 in the til-e mold alid the opening` 42 x in the guide head 15 and has a metallic face plat-e 78 upon the forward end thereof that is secured 'to the follower 77 by the screws 79 that are also employed for Securing the fol- 'lower 77 to the plate 80 which in turn is secured as at 81 to the frame 7 6. When the hinged frame carrying the facing plate 44 is released by the hinged clamp and swung downwardly, and the wire 62 moved between the tile molds and guide head to sever the plastic material, the tile mold is moved on the channel irons 4 and 8 to position the mold in alinement with the follower 77.l Upon operating the pinion 71, the rack bar carrying the follower is moved forwardly to cause the 'follower to enter the design opening in the tile mold to eject the tile.l The finishing treatment of the tile may be accon'iplished in any suitable manner, such as by painting or glazing the design face there` of with other treatments, such as baking or the like.

From the above detail description of the machine, it is believed that the construction and operation thereof will be apparent, and while there. is herein shown and described the preferredembodiment of the present invention, it is nevertheless to be understood gaun ' that minor changes may be made therein without departing from the spirit and scope thereof as claimed.
